Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Related to the vegetation mat using the shell according to the present invention, wherein the vegetation mat using the shell is added to the dehumidification function to prevent early germination of seeds during warming, moisturizing, nutrition and storage by recycling the shell classified as industrial waste , A vegetation mat composed of a moisturizing layer (1), a seed layer (2), a seed protection layer (3), an insulating layer (4), and a protective net (5) in order to improve the mat structure so that the shell recycling throughput can be significantly increased. And a pocket mesh layer 20 in which the compartment 22 is formed.

The vegetation mat according to the present invention is constructed by laminating a moisturizing layer 1, a seed layer 2, a seed protective layer 3, a thermal insulation layer 4 and a protective net 5. The moisturizing layer 1 is formed on the other surface of a biodegradable yarn formed of a polylactic acid (PLA) resin, a PBS-based resin, and an inorganic substance. Moisturizing layer (1) is in contact with the ground to absorb moisture, supply the absorbed moisture to the seed to promote early germination and to prevent necrosis by drought.

Here, polylactic acid (PLA) resin refers to the entire polymer composed of lactic acid (Lactic acid) as a monomer, PLA resin is thermal properties according to the isomer D-Lactide, L-Lactide content and arrangement (random copolymerization, block copolymerization) And physical properties may vary.

The melt index (MI) of the polylactic acid (PLA) resin is preferably 10 to 50 g / 10 min (230 ° C., 2.16 kg load), and the melting point (Tm) measured by DSC is preferably 145 to 230 ° C. . In addition, the melt index of the PBS resin is preferably 1 to 20g / 10min (190 ℃, 2.16kg load). As the melt index is lower, the stiffness and low elongation of the fiber can be imparted, but since the viscosity is lowered, the workability becomes worse. If the melt index is too high, the rigidity of the fiber is not only lowered, but the spinning is difficult.

In addition, the PBS resin is preferably melted alone or mixed with PBS (Polybutylene Succinate), PBSA (Polybutylene Succinate-co-adipate) or PBSF (Polybutylene succinate fumaric).

In addition, the polylactic acid (PLA) resin and the PBS-based resin mixture is melted by injecting inorganic materials at the time of melting, such as inorganic minerals such as mica, gold mica, barium sulfate, titanium dioxide, talc, calcium carbonate (CaCO3), and the like. One or more particles may be mixed. When the inorganic material is mixed to produce a fiber, there is an effect of controlling the filler or crystallization.

The ratio of the mixture at the time of melting the mixture is 50 to 92% by weight, 7 to 45% by weight and 1 to 5% by weight of the polylactic acid (PLA) resin, PBS-based resin and inorganic. Fibers produced in the above range is characterized by excellent physical properties and carding properties when manufacturing nonwoven fabrics.

The biodegradable yarn is prepared in the form of yarn or cotton, it is cut and put into the combiner to inflate and release the lump form and is supplied to the hopper using a back sulfur. The biodegradable yarn supplied to the hopper is quantitatively supplied to the other cotton machine, and then is burnt in an unfolded state to form a moisturizing layer 1.

The moisturizing layer (1) delays natural decomposition for two to four years when the roots of the seeds are activated, thereby preventing soil loss and premature revelation of the construction surface, and absorbs and supplies moisture from the ground. As the growth is accelerated, the roots grow, and the biodegradable yarns that make up the moisturizing layer are released, the roots of the plant easily pass through the moisturizing layer and stick to the ground without damage. It will provide nutrients.

In addition, the seed layer (2) is formed by applying the seed on top of the moisturizing layer (1), this process is carried out by the automated process to form a moisturizing layer (1) on the conveyor line and then seed is applied to the seed It is made in such a way that the layer 2 is formed.

At this time, the seed layer 2 is closed by the seed protection layer 3, the seed protection layer 3, the seed protection layer 3 is a function to prevent the flow of the seed (detaching of the seed and transport to one side during transport or construction) And, it is formed of a pulp or biodegradable film in which a vent hole is formed so as to prevent loss of shell powder stored in the pocket network layer to be described later, and to allow dehumidification inside the seed layer.

In addition, the insulating layer 4 is formed by finishing at least one kind of natural material including the top of the seed layer 2, coir fiber, coco peat, bark, jute, straw, and fallen leaves. Insulating layer (4) is to cut the vegetable natural material and put it into the combiner to inflate, release the lump form and supply it to the hopper using the back sulfur, and the natural material supplied to the hopper is fed to the other cotton machine in the unfolded state (펼쳐) Is formed.

At this time, coir fiber, coco peat, bark, jute are items that depend on imports, so the price fluctuations are difficult and inventory is difficult to secure, it is possible to replace the straw, falling leaves that can be easily secured around the main raw material.

The insulating layer (4) to prevent germination of the warmth and water until the germination after covering the seed after construction, as well as tissues are easily expanded when sprouts of the seed is prevented, sprout damage after seed germination 1 Naturally decomposes in ~ 2 years and functions as natural nutrient

In addition, the protective net (5) is provided on the insulating layer 4 is provided to support the moisturizing layer (1), the seed layer (2), the insulating layer (4) integrally. The protective net (5) is formed by weaving the same yarn as the biodegradable yarn forming the moisturizing layer (1) in a net form, and overlaps the vegetation mat to secure the entire vegetation mat in a manner of fixing the protective net (5) at the top Bonded to the ground.

In addition, the pocket net layer 20 according to the present invention is provided so that a plurality of compartments 22 are formed so that the shell powder 10 is stored between the seed protection layer 3 and the insulating layer 4. Pocket net layer 20 is formed of jute mesh, straw straw mat, or biodegradable yarn network formed by polylactic acid (PLA) resin, PBS-based resin, inorganic material is provided to be naturally decomposed 10-14 months after construction do. That is, the pocket network layer 20 is a space in which the mesh eye of the mesh is formed constitutes the compartment 22. As an example, the pocket network layer 20 is a compartment 22 sidewall compartment by the inclination line above the network structure. Is formed, the partition in the height direction compartment 22 is formed by the thickness of the inclination, and the upper and lower compartments 22 are provided by the insulating layer 4 and the seed protection layer 3 to be finished.

On the other hand, when the pocket mesh layer 20 is formed of straw straw mat, the yarn 22 is processed in a slanted direction by using the straw as the weft to form a compartment 22 in the gap between the straw and the straw.

In the manufacturing process, the seed layer 2 and the seed protection layer 3 are continuously formed while the moisturizing layer 1 is transported through the transfer conveyor, and then the pocket net layer 20 is formed on the seed protection layer 3. At this time, the lower portion of the compartment 22 of the pocket net layer 20 is kept closed by the seed protection layer 3, and then the shell powder 10 supplied to the upper pocket net layer 20 is the compartment ( 22) is stored between, wherein the shell powder 10 is added as much as the thickness of the pocket network layer (20). Subsequently, the thermal insulation layer 4 and the protection net 5 are stacked on the pocket net layer 20 in the laminated state by the sewing line 30 to form an integral vegetation mat.

In this case, it is preferable to use the biodegradable yarns for forming the sewing line 30, the sewing line 30 is bound to support each layer of vegetation mat with the protective net 5 as a whole, in particular the pocket net layer ( Along with the inclination of 20, the sewing line 30 subdivides the compartment 22 in the inclined direction to improve the shell powder oil compartment and the compartment 22 durability.

As such, the shell powder 10 is accommodated and stored in the plurality of compartments 22 formed in the pocket network layer 20, and the thermal insulation layer after the site construction by forming the natural powder layer 21 in the vegetation mat interior space In addition to (4) to improve the winter warming effect, and with the moisturizing layer (1) to delay the moisture evaporation of the ground while absorbing moisture in the rain to help drought, and then is naturally decomposed and used as plant nutrition supply manure .

In addition, since the size of the compartment 22 elastically expands according to the inclination thickness and the tissue density of the pocket network layer 20, the recycling throughput of the shell classified as industrial waste has a significant increase.

In particular, the shell powder (10) stored in the compartment 22 is dried in the form of rolls after forming the vegetation mat due to the pores that have the shell itself while forming a number of pores between the particles to absorb moisture during storage By performing the dehumidification function, the inside of the mat is kept dry at all times, thus preventing the early germination of the rainy season seeds, and having excellent storage properties, thus providing a large amount of inventory for the high season.
